“…Several improvements have been used in PMSM speed control in FW to improve control efficiency and reduce current ripple during voltage limit violation in the FW zone. These methods include the Auto-tuning method [18][19][20], Fuzzy Logic Speed Control [21][22][23][24][25], Improved UDE-Based Flux-Weakening Control [26], and Single Current Regulator Control [27][28][29][30].…”

The paper proposes a new speed control method to improve control quality and expand the Permanent Magnet Synchronous Motors speed range. The Permanent Magnet Synchronous Motors (PMSM) speed range enlarging is based on the newly proposed power control principle between two voltage sources instead of winding current control as the conventional Field Oriented Control method. The power management between the inverter and PMSM motor allows the Flux-Weakening obstacle to be overcome entirely, leading to a significant extension of the motor speed to a constant power range. Based on motor power control, a new control method is proposed and allows for efficiently reducing current and torque ripple caused by the imbalance between the power supply of the inverter and the power required through the desired stator current. The proposed method permits for not only an enhanced PMSM speed range, but also a robust stability in PMSM speed control. The simulation results have demonstrated the efficiency and stability of the proposed control method.

“…A previous study in [22] proposes a CCR‐VQV control scheme which calculates q ‐axis voltage from the d ‐axis voltage guaranteeing constant stator voltage vector amplitude. However, the method in [22] is verified in the asynchronous SVPWM linear region and without control parameter design, where the inverter switching frequency is 20 kHz. This method will be extended in this paper for high power traction motors with a maximum switching frequency in the full‐speed region of 960 Hz, and six‐step operations are achieved to fully unitise the DC‐link voltage.…”

“…In recent years, the focuses of PMSM flux‐weakening control method study are voltage feedback current control schemes [13, 29–32], voltage phase angle control schemes [3], and single current regulator control schemes [22]. The voltage feedback current control schemes apply double current regulators.…”

“…Thus, this paper explores the application of CCR‐VQV in railway traction based on authors' previous study in [22], so as to achieve six‐step operation with low‐switching frequency. Compared with the existing methods, CCR‐VQV can maximise the utilisation of DC voltage and achieve better dynamic performance.…”

Due to the voltage limitation of the inverter DC‐link of railway traction systems, six‐step operations are widely used in the high‐speed region to improve the voltage utilization and increase the maximum fundamental frequency. The magnitude of the output voltage fundamental harmonic reaches the maximum for six‐step operations, while only the phase angle can be adjusted. This limitation makes it challenging to control the instantaneous current of permanent magnet synchronous motors (PMSM). This paper proposes a single d‐axis current regulator flux‐weakening control scheme to improve the current control over six‐step operations of PMSM without changing the inverter output voltage modulation ratio by controlling only one degree of freedom. The voltage in six‐step operations is generated by synchronous space vector pulse width modulation based on basic bus clamping strategy with an effective limitation of the switching frequency in the full‐speed region. A simplified model of the current regulator is developed for the analysis and design of the controller parameters. This paper presents clear rules for entering and quitting six‐step operations effectively to achieve a smooth transition between double current regulators and the single current regulator control. The numerical results are verified by experimental measurements on a 7.5 kW PMSM drive.
